To all whom it may concern:

Be it known that I, ANDREW J. Pn'r'rrr, a citizen of the United States, residing at Fowler, in the county of Otero and State of Colorado, have invented a new and useful Heater and Vaporizer for Engines, of which the following is a specification.

The present invention relates to an attachment for use upon Ford and other automobiles for supplying moistened heated air to the carbureter, whereby to enhance the combustion of fuel in the cylinders and to reduce to a minimum the deposit of carbon in the engine.

It is the object of the invention to provide an attachment of the character indicated to be readily applied and which is so constructed as to carry out the desired objects in an effective manner, the device being simple and inexpensive in construction, and being thoroughly practical and etlieacious in use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is an elevation of the device as applied to the engine.

Fig. 2 is a longitudinal section thereof.

Fig. 3 is a fragmental plan view.

Fig. 4 is a cross section on the line H of Fig. 2.

In-the drawing, there is depicted a conventional hydrocarbon engine of the Ford type, which embodies the intake manifold l to which the carbureter 2 is connected, and the exhaust manifold 3, the radiator of the water circulating system being illustrated at 4.

- The attachment embodies a hood 5 of elongated rectangular form and preferably constructed of sheet metal. This hood embodies an elongated top 6, provided at its inner edge with a relatively narrow depending apron 7 and at its outer edge with a relatively wide depending apron 8. One end of the hood is closed, as at 9, and the rear end of the hood is open, the closed end being disthrough of said bolts, whereby to clamp said I apron in place, thereby supporting the hood over the manifolds.

---An air pipe 11 is secured longitudinally within the hood within the corner between the top 6 and apron 7 and is provided with a lower longitudinal series of air. inlet apertures 12. The rear discharge end of the pipe 11 has attached thereto a downwardly extending pipe 13, the lower end of which is extended forwardly at an angle and eonnected to the air inlet of the carbureter 2 whereby the air flows from the. pipe 11 through the pipe 13 into the carbureter, and from the carburoter into the intake manifold and cylinders. The connection between the pipes 11 and 13 is offset, as at 14:, so as to accommodate and extend over the discharge end of the exhaust manifold 3.

In order to supply moisture to the interior of the hood, an inclined moisture tube 15 is carried by and extends through the closed end 9 of the hood and projects downwardly at an angle so as to extend between the intake and exhaust manifolds, as seen in Fig. 2. Connected to the outer protruding end of the tube 15 is a tube 16 which leads to the uppermost portion of the radiator 4 or water circulating system of the engine, whereby steam and moisture will flow down the tube 16 into the tube 15, and thence into the hood to be drawn with the air into the pipe 11. The air within the hood. will be heated by the walls of the exhaust manifold, thereby also heating and vaporizing the moisture, which will admin with the air and flow through the carbureter. This will fur nish a supply of heated moistened air for the carburetor, to accomplish the desired results.

Having thus described the invention, what is claimed as new is 1. An attachment for engines embodying an elongated hood to be disposed over an exhaust manifold, a pipe extending longitudinally within the hood. adjacent-to the till upper portion thereof and having apertures, and means for connecting said pipe with a carbureter.

2. An attachment for engines embodying an elongated hood having one end open and the other end ciosed and having aprons to be disposed at the opposite sides of an exhaust manifold, and a pipe to supply air to a carbureter extending longitudinally Within the hood adjacent to the top thereof and provided with air inlet apertures.

An attachment for engines embodying a1 elongated hood having one end open and the other end closed and having relatively narrow and wide aprons to be disposed at the inner and outer sides of an exhaust manifold, a longitudinal pipe extending within the hood adjacent to the top thereof and having air inlet apertures, and a downwardly extending pipe connected to the aforesaid pipe at the open end of the hood for connection with a carbureter.

in testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two Witnesses.
